You can: use append hint =20 do the operation with nologging drop the indexes on the target table or set the indexes to unusable and set skip_unusable_indexes at the session level=20 make use of partition exchange make user of oracle's table renaming ability make use of pl/sql's bulk operations (if the insert logic cannot be done in sql) There are probably other possibilities as well.
